If you just want to know how to clear your cache and don't care why, you can skip down to When should I clear my browser cache below.

Your web browser (or browser, for short) is the program that you use to go on the internet. The most popular web browsers are Firefox, Internet Explorer, and Safari. To speed up web browsing, every browser stores some temporary files on your computer so it doesn't have to repeatedly download the same files from the internet. These temporary files are referred to as the browser's cache (pronounced "cash") or temporary internet files.They typically contain copies of images and web pages. The cache is NOT the same as "cookies." That's a different lesson.

Why does FacultyWeb care about my cache?

FacultyWeb is just a web site (albeit a pretty complicated one), which the RenWeb programmers are constantly improving. Three cheers for improvements!! If the programmers make an change to FacultyWeb and your browser's cache has an old copy of some of the program pages, you'll probably get errors. Maybe even the famous Server Error 500!

By the way, the RenWeb desktop program doesn't care about your cache. When the desktop program is updated, you have to download and re-install the whole thing.

When should I clear my browser's cache?

Whenever FacultyWeb displays a message telling you to

Whenever FacultyWeb is giving you errors

Before doing something important like report cards, even if everything seems fine

How do I do it?
